Abstract
Field testing of noise reduction by earplugs was done. Ten factories and 280 employees took 1400 attenuation tests. User molded, expandable acoustic foam, custom molded, and acoustic wool types of earplugs were evaluated. Workers received protection ranging from about 9 decibels at 125 hertz to 29 decibels at 3150 hertz. Acoustic foam earplugs provided the best hearing protection, and acoustical wool, the least. The authors conclude actual noise protection depends on earplug design.
